The answer is d, since air is a muxture of compounds. a way to differentiate between a muxture and a compound is to see it it is a word you would say normally. for example, you would say air on a normal day. however, you wouldn't say carbon monoxide on a normal day.
hope it helped! :)
Answer:
The answer is C
Explanation:
Habitat destruction is the most cause of extinctions. As deforestation continues in tropical forests, it causes mass extinctions among organisms.
All species have specific food and habitat needs. The more specific these needs and the more localized the habitat, the greater the vulnerability of species to loss of habitat to agricultural land, livestock, roads and cities. This is because the organisms are already adapted to the environment and any changes can prove disastrous for them.
In the future, the only species that survive are likely to be those whose habitats are highly protected, or whose habitat corresponds to the degraded state associated with human activity.

Answer:
b. primary motor cortex
Explanation:
The white matter motor pathway is the the corticospinal pathway. This pathway begins at cerebral cortex and ends on interneurons present in spinal cord and lower motor neurons. The pathway controls the limb and trunk movement in the body. There are around one million myelinated neurons in corticospinal track.
The tract also includes premotor areas and primary somatosensory cortex. The neurons mostly begin in primary motor cortex area of the brain. Thus, option B is correct.
